Our result is analogous to the unified framework of Lin, Pass, and Venkitasubramaniam [STOC'09, Asiacrypt'12] that, however, only yields non-black-box constructions of UC protocols.  ...  Our unified framework shows that to obtain black-box constructions of UC protocols, it suffices to implement a special purpose commitment scheme that is, in particular, concurrently extractable using a  ...  We sincerely thank the anonymous reviewers for their incredibly helpful and insightful comments and suggestions.  ...

Round-Efficient Concurrently Composable Secure Computation via a Robust Extraction Lemma [chapter]

We do so by constructing the firstÕ(log n)-round CCA-secure commitment protocol. Our CCA-secure commitment protocol is secure based on the minimal assumption that one-way functions exist.  ...  We consider the problem of constructing protocols for secure computation that achieve strong concurrent and composable notions of security in the plain model.  ...  To construct CCA secure commitments (which is our main technical goal), we instead build upon techniques from prior work on concurrent non-malleable zero-knowledge (CNMZK) [BPS06, GJO10, LPTV10] .  ...

We study the Sign_then_Encrypt, Commit_then_Encrypt_and_Sign, and Encrypt_then_Sign paradigms in the context of two cryptographic primitives, namely designated confirmer signatures and signcryption.  ...  Our optimizations further enjoy verifiability, a property profoundly needed in many real-life applications of the studied primitives.  ...  In case the encryption scheme is not NM-CPA (OW-CCA) secure, such reductions will be useless.  ...

Two-Round Secure MPC from Indistinguishability Obfuscation [chapter]

Additionally the communication in our protocol is only proportional to the input and output size of the function being evaluated and independent of its circuit size.  ...  One fundamental complexity measure of an MPC protocol is its round complexity. Asharov et al. recently constructed the first three-round protocol for general MPC in the CRS model.  ...  Therefore we need to rely on the CCA security of the PKE scheme.  ...

and its efficiency was several orders of magnitude away from known non-covert MPC protocols: Each party was covertly proving that it followed a GMW MPC protocol on committed input by casting it as an  ...  instance of a Hamiltonian Cycle problem, and that proof internally used Yao's garbled circuits for checking correctness of committed values.  ...  Covert Non-Malleable Commitments. It is well-known that CCA-secure PKE implements non-malleable commitment.  ...
